Explanation / Answer

Here,

part A)

f = 41 mm

magnification , m = - 1.50 = - di/do

di = 1.50 * do

1/f = 1/di + 1/do

1/41 = 1/do + 1/(1.50 * do)

solving for do

do = 68.33 mm

the object is located is 68.33 mm

part B)

f = 41 mm

magnification , m = 1.50 = -di/do

di = -1.50 * do

1/f = 1/di + 1/do

1/41 = 1/do + 1/(-1.50 * do)

solving for do

do = 13.7 mm

the object is located is 13.7 mm
